Erg Chebbi — A Gravel Cycling Guide
Erg Chebbi is the great dune field near Merzouga — a 28 km arc of sand reaching 150 m, and the most accessible of Morocco’s ergs. For cyclists it is the dune-edge riding and the desert-camp finish of the Atlas to Sahara Grand Tour, where the crossing ends with sand, silence and a sky full of stars.
The erg
Erg Chebbi is a field of star dunes near Merzouga, running for about 28 km in an arc and reaching up to 150 m. Unlike the remoter Erg Chigaga, it is accessible — the dunes rise directly from the desert plain at the edge of town. The sand is fine and orange, and the light at sunrise and sunset is the reason photographers and film crews come here.
The riding
The riding is the dune-edge piste — compacted desert gravel along the Erg Chebbi fringe, with short sandy sections where the sand encroaches. You do not ride the dunes themselves (the sand is too soft), but the fringe is rideable and spectacular. The Sahara Edge Ride samples it. Erg Chebbi is the finish of the Atlas to Sahara Grand Tour.
Difficulty and surface
The Erg Chebbi approach is moderate terrain. The fringe pistes are rideable but sandier than the Draa corridor, so 45c tyres earn their keep in the soft sections. The real demands are heat, water and navigation on empty, exposed ground. The dunes themselves are too soft to ride — you walk or camel-track them — but the compacted fringe rolls well.
Quick facts
Desert camps
The classic Erg Chebbi experience is a night in a desert camp — a fixed or semi-fixed camp at the dune edge, with dinner, a fire and a sky with no light pollution. The Atlas to Sahara Grand Tour finishes with a sunset camel walk and a camp night. It is the grand finale of the crossing.
Season and water
October to March is the only comfortable window; summer is dangerously hot. Merzouga has water and hotels, but the dune-edge is empty — carry 3–4 L for a ride. See Merzouga and the Sahara guide.
Frequently asked questions

How big is Erg Chebbi?
About 28 km in an arc, reaching up to 150 m. It is the most accessible of Morocco’s great dune fields — the dunes rise directly from the desert plain at the edge of Merzouga.
Is Erg Chebbi the finish of the Atlas to Sahara Grand Tour?
Yes — the grand tour finishes at Erg Chebbi on day six, with a sunset camel walk and a desert-camp night. It is the grand finale of the crossing.
